TRANSMITTER OPERATION

FM TRANSMISSION

Basic Setup/Operation

1.Press the [MODE(t)] or [MODE(u)] key so as to select the FM mode.

2.Press the microphone’s PTT switch, and speak into the microphone in a normal voice. Release the PTT switch to return to the receive mode.

3.If you get reports that your modulation level is too high or too low, you may need to adjust the FM-mode microphone gain. The procedure is similar to that used on SSB:

ŸPress the [FUNC] key momentarily, then rotate the SELECT knob, as needed, until Multi Function Row “i” [MTR, PWR, DISP] appears on the display, then press the [A](MTR) key to select the “Deviation” meter function (“MOD” will appear above the [B] key).

4.Press and hold in the [FUNC] key for one second to enter the Menu mode.

5.Rotate the SELECT knob to recall Menu Mode No-001[EXT MENU], then rotate the DIAL to change the setting to “ON” to enable the extended Menu Mode.

6.Rotate the SELECT knob to recall Menu Mode No-051[FM MIC GAIN].

7.Rotate the DIAL to increase or decrease the setting of the FM Mic Gain, depending on the level correction required.

8.Close the PTT switch, and while speaking into the microphone observe the

meter indication; the proper setting of the FM Mic Gain will produce 16 “bars” of indication on voice peaks, slightly less on lower levels of speech input.

9.When done, press and hold in the [FUNC] key to save the new setting for the FM-mode microphone gain.

10.The VOX feature is operational during FM transmission. From Multi Function Row “d” [RPT, REV, VOX], press the [C](VOX) key to activate/deactivate VOX.

FT-857 specifications

The Vertex Standard FT-857 is a compact and versatile all-mode transceiver that has become popular among amateur radio operators since its introduction. With its ability to operate in VHF, UHF, and HF bands, the FT-857 caters to a diverse range of communication preferences and provides exceptional performance for both mobile and base station applications.

One of the key features of the FT-857 is its coverage of a broad frequency range, spanning from 160 meters to 2 meters and covering the 70 cm band. This wide frequency coverage allows amateur operators to communicate with fellow enthusiasts across various bands, ensuring versatility in operational environments. The FT-857 offers an output power of up to 100 watts on HF and 50 watts on VHF/UHF, providing sufficient power for effective communication, whether in local or distant contacts.

Another distinctive characteristic of the FT-857 is its all-mode capability. It supports various modes of operation, including SSB, CW, AM, and FM, making it suitable for different operating styles and preferences. The inclusion of advanced digital signal processing (DSP) technology enhances audio clarity and offers noise reduction features, which are crucial in crowded bands. This DSP capability also aids in improving signal quality and overall communication experience.

Portability is a significant advantage of the FT-857. Its compact size and lightweight design make it an excellent choice for field operations and portable setups. Additionally, the transceiver is well-equipped with features such as built-in memory channels, allowing users to save and quickly access frequently used frequencies. The FT-857 also includes a built-in automatic antenna tuner, which makes it easier for operators to set up and optimize their antenna configurations without requiring additional external devices.

The FT-857 is designed with user-friendly controls and a clear LCD display, enabling operators to quickly adjust settings and monitor communication details without confusion. The visibility of the display is especially vital for use in different lighting conditions, ensuring that users can operate efficiently whether in bright sunlight or low light conditions.

In summary, the Vertex Standard FT-857 is a highly capable, compact transceiver that offers an effective solution for amateur radio communication. With its all-band, all-mode capabilities, robust DSP technology, and user-friendly design, the FT-857 remains a popular choice for both enthusiasts and professionals alike, facilitating engaging communication experiences across multiple bands and modes.
